Abstract

A recloseable biosensor is provided that comprises a substrate, a sample site positioned on the substrate, and an openable and recloseable cover coupled to the substrate. The cover is operative to selectively block access to the sample site. The cover includes a fixed end coupled to the substrate, an opposite free end, and a middle portion extending across the sample site. The middle portion is releasably and recloseably adhered to the substrate.
